Relevance of Laser Flare Photometry in Retinal Pathologies.

Laser flare photometry provides a non-invasive and objective measurement of the Tyndall effect in the anterior chamber. The laser flare value (measured in photon number per millisecond [pc/ms]) thus quantifies the extent of disruption to the blood-aqueous barrier and can be used in clinical applications to monitor uveitis therapy or to measure the postoperative degree of inflammation. Standardised performance must be observed during measurement.

Retinal and Choroidal Ultra-Widefield OCT - Technology, Insights, and Clinical Relevance.

As one of the most state-of-the-art procedures for retinal and choroidal imaging, ultra-widefield optical coherence tomography (UWF-OCT) offers significant gains in terms of information pertaining to peripheral retinal lesions and their differential diagnoses. In particular, it enables the presence of minimal accumulations of subretinal fluid to be assessed in detail and then documented. It also enables choroidal expansion of choroidal lesions to be precisely measured.

Regenerative approaches as alternatives to donor allografting for restoration of corneal function.

A range of alternatives to human donor tissue for corneal transplantation are being developed to address the shortfall of good quality tissues as well as the clinical conditions for which allografting is contraindicated. Classical keratoprostheses, commonly referred to as artificial corneas, are being used clinically to replace minimal corneal function. However, they are used only as last resorts, as they are associated with significant complications, such as extrusion/rejection, glaucoma, and retinal detachment.

A new tool for the transfection of corneal endothelial cells: calcium phosphate nanoparticles.

Calcium phosphate nanoparticles (CaP-NP) are ideal tools for transfection due to their high biocompatibility and easy biodegradability. After transfection these particles dissociate into calcium and phosphate ions, i.e.
